Sierra Anode Kit 18-6159A, Aluminum, for Mercruiser Bravo I Sterndrives

The Sierra 18-6159A Anode Kit is an aluminum sacrificial anode set built for Mercruiser Bravo I sterndrives. Sacrificial anodes protect the more expensive metal components of a sterndrive from galvanic corrosion by corroding first, so replacing worn anodes on a regular schedule is one of the simplest ways to extend the service life of the drive. This kit uses aluminum anode material, which is a common choice for boats operating in brackish or fresh water as well as salt water.

Sierra manufactures this kit to meet or exceed the performance of the original equipment it replaces, and every Sierra part is backed by Sierra's customer satisfaction warranty. Sierra supplies OEM engine manufacturers and boat builders with parts daily, so the fit and finish are built to marine duty-cycle standards.

This anode kit is intended for Mercruiser Bravo I sterndrives, across all years of that drive. Boat owners should inspect anodes periodically and replace them once they are worn down significantly, since a depleted anode can no longer protect the drive's metal components from corrosion.
